Nordic Pure 25x28x1CustomM12+C-6 Merv 12 Carbon Filter 6pk

Product Description

The NORDIC PURE 25x28x1CustomM12+C-6 is a custom-cut, pleated MERV 12 Plus Carbon air filter sold in a 6-pack, designed for residential and light-commercial HVAC systems including forced-air furnaces and central air conditioners. With an actual size of 24.5 x 27.5 x 0.75 inches, this filter is hand-fabricated to match non-standard filter cavities where off-the-shelf sizes do not fit. The MERV 12 rating means it captures more than 90 percent of airborne particles between 3 and 10 microns, and 80 to 90 percent of particles between 1 and 3 microns. An activated carbon layer addresses odors alongside particulate filtration. Licensed HVAC technicians and experienced installers handle these as direct drop-in replacements during routine maintenance cycles.

This filter is suited for residential forced-air furnaces and central AC systems with non-standard or oversized filter slots that require a custom nominal size of 25x28x1. The 6-pack format supports a full service rotation for a single system. Recommended replacement interval for 1-inch thick filters is every 30 to 90 days depending on household conditions such as pets, dust load, and local air quality. The activated carbon layer makes this filter a practical choice for installs where odor control alongside particulate capture is a priority. Frames are constructed by cutting down or combining standard filter frames, with tape reinforcement used as needed to achieve the target dimensions.

Key Features

Compatibility

Designed for forced-air furnace and central air conditioning systems with a non-standard filter slot requiring a nominal 25x28x1 size. Verify the actual opening dimensions before ordering. The actual filter measures 24.5 x 27.5 x 0.75 inches; the actual width and length of the filter opening should be within 1/8 inch of those values for a proper fit.

Installation Notes

A licensed HVAC technician or qualified installer should set the system to the off position and shut down power at the disconnect or breaker before replacing the air filter. Confirm airflow direction arrows on the filter frame align with the system airflow direction before seating the filter. Because this is a custom-made product fabricated to the exact dimensions listed, verify measurements with a tape measure prior to ordering. Follow local mechanical codes and the system manufacturer service instructions for filter change intervals and disposal procedures.
